btrfs vs ext4?on Which partition?
For me, stability and less battery consumption is much important

I don't know how current this information is, but to quote wikipedia:

Btrfs (B-tree file system, variously pronounced "Butter F S", "Butterfuss", "Better F S",[4] or "B-tree F S"[5]) is a GPL-licensed experimental copy-on-write file system for Linux. Development began at Oracle Corporation in 2007. It is still in heavy development and marked as unstable. Especially when the filesystem becomes full, no-space conditions arise which might make it challenging to delete files.

I would use ext4 if you want stability.

As for battery consumption, there are several tricks that can save you a few percent each: dimming the screen, switching off wireless technology when you do't need it, spinning down hard drives, trottling the CPU, reducing the network bitrate, switching off the graphics card if you also have lower performance on-board graphics, et cetera.

Use ext4, unless you need a btrfs feature that ext4 lacks (and if you have to ask, you probably don't).

Live on the edge and try btrfs. If it works for you, great. If it breaks, you get to keep the pieces.

Neither one will affect power consumption.
